A device for backfilling and sealing layers after drilling for engineering investigation

Abstract

The invention relates to a device for backfilling and sealing layers after drilling in engineering survey, including a mold lower frame, a driving device, a connecting plate, a middle cutting tube, an edge cutting device, a clamping device, a No. 1 crushing device and a No. 2 crushing device , the left end of the mold lower frame is equipped with a driving device, the upper end of the driving device is equipped with a connecting plate, the middle part of the connecting plate is installed with a middle cutting tube, the outer side of the connecting plate is evenly equipped with an edge cutting tube along its circumference, and the middle cutting The left and right ends of the barrel are symmetrically equipped with locking devices, the inside of the middle cutting barrel is equipped with a No. 1 smashing device, and the inside of the edge cutting barrel is equipped with a No. 2 smashing device. The present invention can solve the problem that when the existing clay balls are crushed, the input amount of the clay balls should not be too much at one time, and too much input will easily cause blockage, and the gap between the crushed clay balls is still large, and manual crushing is usually difficult for the drill. The middle part of the hole is smashed, which makes it difficult for the tool to reach the clay block at the dead corner of the hole.

Description

technical field [0001] The invention relates to the field of backfilling and sealing layers of boreholes, in particular to a device for backfilling and sealing layers after drilling for engineering investigation. Background technique [0002] Drilling is the most intuitive form of obtaining engineering geological information, and it is also one of the most important means in the stage of engineering exploration. Among them, the backfilling of the borehole is the last important link in the drilling process, and artificial , livestock falling into it, and surface pollution flowing into groundwater from boreholes. Therefore, it is very important to backfill the boreholes. During the backfilling process, clay balls need to be crushed and then compacted on the soil layer. However, now The following problems often occur during the crushing process of some clay balls: [0003] 1. The amount of clay balls should not be too much at one time, too much input will easily cause blockage...

Problems solved by technology

[0006] The present invention can solve the problem that when the existing clay balls are crushed, the input amount of the clay balls should not be too much at one time, and too much input is likely to cause blockage, and the clay balls need to be crushed and dredged after the input. Most of the methods are manual crushing, and the gaps between the crushed clay balls are still relatively large. In order to avoid damage to the surroundings of the drill hole caused by the crushing tools, the manual crushing usually crushes the middle of the drill hole, resulting in tools and The clay block at the dead corner of the drill hole is difficult to reach, making the clay ball particles in this part larger, etc.
